Micro gas turbine generator set

Abstract

The invention relates to the technical field of engine equipment, in particular to a micro gas turbine generator set, which comprises an electric generator, a gas compressor and a turbine, a combustion chamber and a nozzle. The electric generator, the gas compressor and the turbine are mounted on a rotating shaft; an outlet end of the nozzle is inserted into the combustion chamber; an exhaust endof the gas compressor is in communication with the combustion chamber; and an exhaust end of the combustion chamber is in communication with the turbine. The micro gas turbine generator set further comprises a heat regenerator; the heat regenerator is provided with a first channel and a second channel that are isolated and in close contact with each other; an inlet of the first channel is in communication with the exhaust end of the gas compressor; the outlet of the first channel is in communication with the combustion chamber; and the inlet of the second channel communicates with the exhaustend of the turbine. The air entering the combustion chamber can be preheated through the heat regenerator, thereby improving the temperature of the air entering the combustion chamber and further improving the combustion efficiency, reducing the content of pollutants in the exhaust gas and reducing the temperature of the exhaust gas at the same time.

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to a micro gas turbine generating set. Background technique [0002] When the micro gas turbine generator set is working, it first continuously sucks in air from the atmosphere through the compressor and compresses the air. After mixing, it burns to generate high-temperature and high-pressure gas; the generated high-temperature and high-pressure gas then enters the turbine and expands to do work, driving the turbine to rotate and driving the compressor and generator to rotate together at high speed, realizing the partial conversion of the chemical energy of gas or liquid fuel into mechanical work and output electric work. [0003] Before the compressed air enters the combustion chamber, it is only compressed to increase its temperature without further heating, resulting in insufficient temperature when it enters the combustion chamber, resulting in low combustion efficienc...

AI Technical Summary

Problems solved by technology

Most of the regenerators in the current technology are circular and take up a lot of space; especially when using a car, it is inconvenient to install and arrange

Another point is that the heat transfer efficiency and size of the regenerator in the current technology are fixed, and it cannot be assembled at will according to different heat transfer requirements. Only a regenerator can be redesigned, which will increase the cost of the regenerator and the micro gas turbine generator.
